INSULATED WALL.

' applicati@ ala February 16, `1925. 'serial Nq. 9,642.

Myinven'tion relates to means for. providing monolithic insulation between spaced wall elements.

lIt has been determined that in order to secure efficient heat insulation, it is necessary to provide a thickness of insulating material p Y 12 are broken away at :one side L and laid in at some point inthe vertical walls. This is particularly desirable in order to suitably insulate the walls of ice houses and similar buildings. It has been found that masonry or hollow tile does not provide the necessary insulation and it has been customary to build'masonry or tile `walls of double thickness, leaving an intervening space which is filled with a fibrous or other insulating substance. However, such insulation is expen-v sive and ineffective in some particulars A strong objection is that there is no bond thus provided between the adjacent wall sections.

It is the object of my i vention to provide an improved form ofwal by a novel method in accordance with which a .plastic expan- -siblematerial is poured between spaced wall sections-so as to set and harden in cellular form and to .adhere to such wall sections so as to serve as a bond between them. It is invention to increase the bonding effect, such as by breaking out parts of the materials of of the construction whereby the cellular 'I provide a, method and bonding 'material' may have on the wall sections.

. It is another obJeot-of my invention vto construction of this t e. which/ can be employed by the ordinary s lled workman, which'can be employed to 'advanta e atllow expense whichl e ective insulation may be obtained. It is still another object of my invention to provide 'sundry improvements as hereinafter set forth.

.'The invention will be more readily understood by 'reference to the raccompanying dryying, in which 1g. a brick wall constructed in accordance w1 my invention.

after each pouring operation before a second. batch is vmixed and poured thereon. As this materialis pouredinto place, it enters the recesses formed by the roken bricks and serves. to increase the bonding effect of theplastic material. The character ofv this materialis such, however, that it strongly adheres tothe masonry faces and provides a bond between the wall sec- In the tions even when the bonding recesses are not. rovided.

hile I 'prefer to employ the type of porous cellular material as disclosed and claimed in my prior patent as above suggested, I do not'desire to be limited to any particular proportions of ingredients orto any particular form ofI material, except as the same is specifically claimed. IV have obtained very terials mixe poured into place with water on 'the job and between the wall sections,

such-materials consisting of 100pounds of' calcined gypsum, 31/2 ounces Vof commercialA retarder, 6% pounds of a -suitable carboncarbonate, and 121/2 water of crystallization, all of such ingredimixed in adry state.

In the constructions .shown in Figs. 2 and 4, the wall is composed of hollow tiles laid to provide wall sectionsl and 14 suitably spaced apart. In the vinstallation of the tiles,' hen a strong bond isl Arequired bethe workmen break of certain of the in order good results by the use of mav crease the bonding effect. The preparation and pouring of the plastic material are the same as that described in connection with the brick wall -construction.

In practical use, a coating or layer of a. waterproof substance maybe applied to the inside face of one of the wall e1ements5 preferably the outer wall element;- With such vwaterproof coating in use, the condensation of moisture` in the insulating material will be avoided without interfering in any way with the adhesion of my cellular material to the Wall element'. y. Y n

The efective insulation of vertical walls ,is accomplished very simply and economically. While I have illustrated walls as com' posed of two spaced masonary sections, it will be understood a similar result is se. cured even though one of the wall-sections is composed of masonry and-another of a i' diierent material. 'I do not .wish to be limited-except as indicated in the appended claim.

I claim:

A'iwall comprisin in combination two supporting wall sections in spaced relationV to each other, at leastV one of said sections being built up principally of hollow tiles with some of the tiles at intervals throughout the' face of the wall sec-tion provided with openingsV into the interior hollow spaces yand a monolithic body of cellular insulating material filling the space between sadtwo sections and extending through said openings into the interiorl spaces of 'the `tiles serving both to insulate the wall and also mechanically to bond the two sections to-` gether.
